Investor Verification Checklist
- Verify the final approved revenue requirement and rate base adjustments by the OPUC, as the $154.9 million figure is a request, not a guarantee.
- Monitor the timeline for the rate case resolution to confirm if the November 1, 2024, effective date is met.
- Review the company's most recent Form 10-K for historical financial performance and detailed risk factors not fully elaborated in this 8-K.
- Assess the impact of the proposed 10.1% return on equity and 7.406% cost of capital against current market rates for similar utilities.
